Hello, I need some descriptors of MPEG7 in Matlab. The descriptors are dominant color, color layout, color structure, scalable color, edge histogram and homogeneous texture. Do you know where can I find Matlab source code for these descriptors? Thanks ...
I've got a Sony network camera (SNC-RZ25N) that I am trying desperately to get data from in some meaningful format. The documentation says it sends MPEG-4 raw data, but is not more specific than than. I can capture a segment of the stream using curl ( http://techhead.biz/media/tsv.m4v ) and it will play using VLC and ffplay (though it pl...
Hi, Quicktime-, MPEG- or AIFF-files all seem to organize their data elements in chunks like this: 0x00 chunk 1 header (size as UInt32 + ID as 4-char-code) 0x08 chunk 1 data ... 0xA0 chunk 2 header 0xA8 chunk 2 data ... and so on. When reading a file like that, it's easy to skip to the chunk of interest, because each chunk declares it...
I am trying to create a 30 second sample from a 2 minute MPEG-4 video. We are looking for a 100% java solution as an alternative to ffmpeg. So far, we have tried IsoParser, which lacks example code and documentation splitting MPEG-4. Has anyone used this tool or others to create cut/split MPEG-4 video? ...
Hello, I need some descriptors of MPEG7 in C/C++. The descriptors are dominant color, color layout, color structure, scalable color, edge histogram and homogeneous texture. Do you know where can I find C/C++ source code for some of these these descriptors? Thanks ...
I am working on one of the media project (windows application). In this the flv, avi and mpeg are the main file types which i have to play in application. I can use wmpLib, but it will not play flv files. So what procedure should i follow and what tools or libraries should i use.Is there any free opensource libraries to do media work. Th...
I have an iPhone application that uses small MPEG movies showing hand signs in the Dutch Sign Language. I get the movies from the Gebarencentrum, with their permission. But they are all in the old MPEG-1 format, and the iPhone won't play that. The allowed me to convert a couple of hunderd of the movies in batch and put them on my own web...
Does anybody know of a simple dll that has like 3 main functions, i.e. 1. Start_recording_mpeg(<encoding>, <fps>, <file>, <etc>) 2. Encode_frame(<raw rgb data>) 3. Finish() ...
Given a MOV file, is there a way supported by the iphone-sdk to allow for reading of the mpeg4 header information? There are a bunch of classes for this exact thing for OSX obj-c but I have yet to find anything for the iphone. The other option is to open the file and parse the header information myself but it seems like a painful thin...
Hey everybody I'm stuck with a basic problem in my MPEG-1 compression. I have to produce macroblocks within a image. A macroblock consists of 16 x 16 pixels - where 4 x 8x8 is luminance, 1 x 8x8 is Cb and 1 x 8x8 Cr. In MATLAB I want to produce a cell matrix containing this. Any suggestions? ...
I've tried MediaElement with a .ts file - its not interested (HRESULT: 0xC00D11B1). The TS file plays with WMP no problems (Cannot seem to play it in graphedt though?) I thought MediaElement was supposed to support what WMP supported? Update: This is on Windows 7 by the way (apparently it has a slightly different media stack if that m...

I want to convert folders with video-frames in bitmaps into avi or mpeg files. I already have a VBScript which does a lot of stuff on those files, so it would be neat to integrate a functionallity to convert those folders automatically from my script. I can only find solutions that seem pretty low level and unfortunatley I don't know a w...
I am considering using the excellent looking Cocos2d for a motion graphics project. However, Cocos2d is intended for games, rather than producing an MPEG stream. Is it possible to save the output from a Cocos2d script to a MOV or MPG file? Ideally this needs to be done in a direct manner, not using a screen capture as this would not mee...
I'd like to be able to take a screenshot of an MPEG recorded using the iPhone camera at set intervals. I've seen a few ways to do this; namely compiling and using FFmpeg (http://stackoverflow.com/questions/1679649/using-ffmpeg-library-with-iphone-sdk-for-video-encoding), however it seems it's quite difficult to comply with the LGPL (htt...
Hi there, can anyone recommend a MPEG4 library that will compile(or is compatible) with Intel or Visual C++? EDIT: clarification I was not aware of x264, and ffmpeg does not compile with VC++ (compiles with MingW). Basically I need a library that can be compiled on Windows (or the name of a vendor) that will allow me to extract frames ...
I'd like to add video conversion capabilities to a program I'm writing. FFmpeg's command line interface for doing this is simply ffmpeg -i InputFile OutputFile, but is there a way to make use of it as a library, so I can do something like ffmpeg_convert(InputFile, OutputFile)? I'm hoping I won't have to use libavcodec directly, as I ima...
Hi I have a camera that sends h264 mpeg video over rtsp. I am looking for a solution in .NET to save this stream to disk as either a movie file or in some format I can later 'restream'. Have so far, without success, attempted to use vlclibnet for this but am unable to reliabely get it captured to a file. Any suggestions? Thanks ...
My hardware (video capture card) gives me the images in YV12 (YUV 420) format and I am trying to generate a video from it. I am using C++ under windows and I would like to generate a mpeg-4 VBR video from that stream but I dont know where I should start... (I need it to be VBR because it is a security camera and there will be a lot of re...
Hi, I've set up FFserver as the streaming server. I'm trying to feed in an mpeg file. But it comes up with a segmentation fault. Does anyone know how to fix this?
